Abstract

Device for deviating gas flows in aerosol-producing nebulizers in the breathing and rebreathing regions of a respiratory appliance comprises a bypass device. When the gas flows in one direction it takes the aerosol with it and when the gas flows in the other direction it bypasses the aerosol at the nebulizer via a bypass. An independent claim is also included for a device for supplying gas flows in nebulizers in breathing and rebreathing regions of a respiratory appliance comprising a valve timed by the respiratory appliance so that the dead space is not filled with aerosol.
